JOHN C. MGLACHLAN, OF PATTERSON, ONTARIO, CANADA, ASSIGNOR TO PETER PATTERSON, OF SAME PLACE.

CORD-HOLDER FOR HARVESTER-BINDERS.

.QBIPECL'FICATION forming part of Letters Patent No. $13,094:, dated March 3, 1885.

Application filrd May 28. 1893.

To all whom it may concern.-

Be it known that T, JOHN CAMPBELL Mo- LAOHLAN, of the village of Patterson, in thecounty of York, in the Province of Ontario, Dominion of Canada, have invented certain new and useful Improvements in Cord-Holders for Harvester-Binders, of which the following is a specification.

The invention relates to certain new and useful improvements in cord-holders for harvester-binders; and it consists in the peculiar combinations and the construction and arrangement of parts, hereinafter more fully de scribed and claimed.

Figure l is aperspective view of the binding mechanism, showing the needle extending through the needle-slot in the breast-plate and carrying the cord into the knotting mechanism, portions of the needle and the knottershaft being broken away. Fig. 2 is a face view of the holding-wheel. Fig. 3 is a horizontal section of the holding-wheel and holder.

In the class of binders in which my invention is employed the holding device for secur ing the cord while being knotted is frequently defective, insomuch that the cord must be of a uniform thickness; otherwise it will not be satisfactorily held-that is to say, it slips from the holder if of less diameter than that for which the holderis constructed, or,if of greater diameter, itis cut or crippled by being-jammed between the jaws of the holding-wheel. By my invention this defect is effectually overcome.

In the drawings, A is the breastplate. B is the stripper. (J is the holding-wheel. D is the needle. E is the needle-slot in the breastplate A. F is the cord, which has been carried by the needle around the sheaf and into one of the notches in the holdingwheel. G is a flaring flange or horn extending from the string-guiding edge of the stripper B obliquely across the needle-slot E, and terminating in the recess g, formed in the stripper opposite the knotting-hook H. I make no claim, however, in this application to the stripper.

On reference to Fig. 3 it will be noticed that the holding-wheel O is wedge-shaped, the taper of the wedge extending from a little below the notches a to the periphery of the wheel. It

will also be noticed that the jaws J ofthe holder are flared out at an angle to correspond with the taper of the holding-wheel. It thus follows that the cord F, when fitting into the .notch c and carried by the movement of the wheel between the flaring jaws J of the holder, will be gripped evenly on both sides of the holder-wheel from the bottom of the notches a to the outer edges of the jaws J. Thus a firm, easy, and even grip on the cord is insured. The holder J is supported by the yield ing spring K. This form of holding mechanism permits different sizes of cord to be used in the binderthat is to say, when thin cord is used the periphery of the holding-wheel 0 extends into the holder nearer to the bottom of the jaws J than when a thicker cord is used, the spring K behind the holder permitting it to yield to accommodate it to the different thicknesses of the cord.

On reference to Fig. 2 it will be noticed that each notch a has one of its sides chamfered off, so as to form a hook on the side of the notch so chamfered off. This chamfered side of the notch is the side which will come in contact with the cord as the wheel draws the cord down into the holder J, and is so chamfered for the purpose of forming a hook at the top of the upper edge of the notch, in order to prevent the cord slipping out of the notch as it is being drawn down by the wheel into the holder.

In Fig. 1 I show an improved tucker, L, which 1 do not intend to cover in this application, rcserving the right to do so in a future one.

Vhat I claim as my invention is- 1. In a harvester-binder in which the cord is carried into a notch in a holding-wheel, the combination of said wheel with a holder having flaring jaws and held toward the wheel by a spring.

2. In a harvester-binder in which the cord is carried into anotch in a holding-Wheel ar- 3. In a harvester-binder in which the cord before knotting is gripped between a notched 10 is carried into a notch in a Wheel arranged to wheel and a flanged holder, a holding-wheel carry the cord betweenjaws for gripping the I having one side of each notch chemfered 0ft said cord, aholder having flaringjaws, in com- I so as to form a hook on one side of the notch. bination with a wedge-shaped notched wheel, T the taper of the Wedge extending from a little MGLAOHLAL below the notches to the periphery, and cor- Witnesses: responding with the taper 0f the flaring jaws.
